Description

Technical Field

[0001] The utility model relates to the technical field of electric power, and in particular to a multifunctional integrated grid-connected device for a new energy station. Background Art

[0002] Photovoltaic power generation systems can be divided into off-grid photovoltaic power generation systems and grid-connected photovoltaic power generation systems. The investment in grid-connected photovoltaic power generation systems is 25% lower than that in off-grid photovoltaic power generation systems. Connecting photovoltaic power generation systems to the large power grid in the form of microgrids and supporting each other with the large power grid is an important technical solution to increase the scale of photovoltaic power generation. The grid-connected operation of photovoltaic power generation systems is also the main direction of future technological development, and the grid-connected photovoltaic power generation naturally requires the use of photovoltaic grid-connected devices.

[0003] The publication number is CN207098635U, which discloses a low-fault photovoltaic grid-connected device, comprising a photovoltaic grid-connected device box, a device box door is movably connected to the left side of the front of the photovoltaic grid-connected device box, an air outlet is fixedly connected to the inner left wall of the photovoltaic grid-connected device box, one end of the air outlet away from the inner left wall of the photovoltaic grid-connected device box passes through the inner right wall of the photovoltaic grid-connected device box and extends to the right side of the photovoltaic grid-connected device box, and a motor is fixedly connected to the inner bottom wall of the photovoltaic grid-connected device box. The low-fault photovoltaic grid-connected device reduces the probability of failure of the photovoltaic grid-connected device by arranging a motor, a rotating shaft, fan blades, a heat dissipation pipe and an air suction port, and effectively solves the problem of failure of the photovoltaic grid-connected device due to long-term use.

[0004] Based on the above technical features, the defect is that the machine body is placed inside the photovoltaic grid-connected device box. When the machine body works for a long time, a large amount of heat will be generated, causing the temperature inside the photovoltaic grid-connected device box to continue to rise. After the temperature rises, it is easy to cause a short circuit in the machine body and thus a failure, thereby causing part of the power grid to be paralyzed, and even causing a fire. Although this device cools down the temperature of the photovoltaic grid-connected device box through a motor, a rotating shaft, fan blades, a heat pipe and an air intake, it is difficult to achieve a good heat dissipation effect only through the fan blades, which will still cause the temperature inside the photovoltaic grid-connected device box to rise.

[0005] Therefore, it is necessary to solve the above problems through a multifunctional integrated grid-connected device for new energy stations. Summary of the invention

[0006] The purpose of the utility model is to provide a multifunctional integrated grid-connected device for a new energy station to solve the problems raised in the above-mentioned background technology.

[0010] Preferably, second racks are provided on both sides of the interior of the first frame, fourth racks are provided on both outer ends of the third frame, and the second rotating wheel is meshingly connected with the second rack and the fourth rack.

[0011] Preferably, the supporting mechanism comprises connecting blocks, and the connecting blocks are distributed on both sides of the front ends of the first frame body, the second frame body and the third frame body, and are arranged from bottom to top.

[0012] Preferably, a support plate is provided at the other end of each of the connection blocks, and there are three support plates, which are arranged from bottom to top.

[0016] Preferably, a dust screen, a fan and a ventilation hood are arranged inside and outside the channel in sequence.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The heat dissipation mechanism of the utility model moves to deliver cold air to the inside of the photovoltaic grid-connected device box. The supporting mechanism is lifted by the lifting mechanism to expand the gap between the supporting mechanisms, so that the cold and hot air can be alternated quickly to dissipate the heat inside the photovoltaic grid-connected device box, thereby avoiding the internal temperature of the photovoltaic grid-connected device box being too high and affecting the use of the device.

[0019] 2. When the sliding block of the utility model slides in the sliding groove, the position of the lifting mechanism is limited to prevent the motor from driving the threaded rod to rotate. During the process of the threaded rod rotating the lifting plate to lift and lower, the lifting plate rotates, thereby ensuring that the lifting mechanism only moves up and down. At the same time, the sliding groove limits the position of the support plate and the lifting plate to prevent the lifting plate from rising too high, and at the same time, prevents the first transmission wheel and the second rotating wheel from detaching from the racks, making the lifting mechanism unusable, thereby ensuring the movement stability of the support mechanism and the lifting mechanism.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figures 1 to 6 A multifunctional integrated grid-connected device for a new energy station is shown, comprising a photovoltaic grid-connected device box 1, a lifting mechanism 4 is arranged inside the photovoltaic grid-connected device box 1, a supporting mechanism 5 is arranged at the front end of the lifting mechanism 4, sliding grooves 7 are relatively opened on both sides of the interior of the photovoltaic grid-connected device box 1, the sliding grooves 7 are slidably connected to the supporting mechanism 5, a heat dissipation mechanism 2 is arranged on one side through the top of the photovoltaic grid-connected device box 1, and temperature sensors 3 are arranged on both upper and lower sides of the rear end of the interior of the photovoltaic grid-connected device box 1.

[0029] When in use, the temperature inside the photovoltaic grid-connected device box 1 is detected by the temperature sensors 3 on the upper and lower sides. The temperature sensors 3 on the upper and lower sides can detect the temperature inside the photovoltaic grid-connected device box 1 more accurately. Due to the characteristics of hot air descending and cold air rising, the temperature sensors 3 are installed on the upper and lower sides to more accurately detect the inside of the photovoltaic grid-connected device box 1. When the temperature is too high, the heat dissipation mechanism 2 moves to deliver cold air to the inside of the photovoltaic grid-connected device box 1. The supporting mechanism 5 is lifted by the lifting mechanism 4 to expand the gap between the supporting mechanisms 5, so that the hot and cold air can alternate quickly, and the inside of the photovoltaic grid-connected device box 1 can be dissipated to avoid the internal temperature of the photovoltaic grid-connected device box 1 being too high and affecting the use of the device.

[0030] The lifting mechanism 4 includes a motor 401, which is fixed inside the photovoltaic grid-connected device box 1. A threaded rod 402 is arranged at the output end of the motor 401, and a lifting plate 404 is arranged on the outer cylindrical surface of the threaded rod 402. A first frame 405 is arranged at the top of the lifting plate 404, a second frame 406 is arranged inside the first frame 405, a third frame 407 is arranged inside the second frame 406, and the bottom ends of the second frame 406 and the third frame 407 are both arranged on the end surface of the lifting plate 404.

[0031] Through holes are provided on both sides of the first frame body 405 and the second frame body 406, and the first rotating wheel 4010 and the second rotating wheel 4011 are arranged inside the through holes. The first rotating wheel 4010 is located inside the through hole of the first frame body 405, and the second rotating wheel 4011 is located inside the through hole of the second frame body 406. First racks 403 are arranged on both sides of the interior of the photovoltaic grid-connected device box 1, and third racks 409 are arranged on the outer ends of both sides of the second frame body 406. The first rotating wheel 4010 is meshed and connected with the first rack 403 and the third rack 409.

[0032] Second racks 408 are disposed on both sides of the first frame 405 , fourth racks 4012 are disposed on both outer ends of the third frame 407 , and the second rotating wheel 4011 is meshedly connected with the second rack 408 and the fourth rack 4012 .

[0033] The supporting mechanism 5 includes connecting blocks 503 , which are distributed on both sides of the front ends of the first frame body 405 , the second frame body 406 , and the third frame body 407 and are arranged from bottom to top.

[0034] When in use, when lifting is required, the motor 401 rotates to drive the threaded rod 402, the threaded rod 402 drives the lifting plate 404 to lift, the lifting plate 404 drives the first frame 405 to rise, and at the same time, the first rotating wheel 4010 on the side wall of the first frame 405 rotates along the direction of the first rack 403, the first rotating wheel 4010 is meshed with the third rack 409 installed on the outside of the second frame 406 through the first rack 403, the first rotating wheel 4010 rotates between the first rack 403 and the third rack 409, and while the first rotating wheel 4010 rotates, it will drive the second frame 4 06 rises, and when the second frame body 406 rises, it will drive the second rotating wheel 4011 to rotate, and the second rotating wheel 4011 moves along the direction of the second rack 408 on the inner side wall of the first frame body 405. At the same time, the fourth rack 4012 on the outer side of the third frame body 407 engages with the second rotating wheel 4011, driving the third frame body 407 to rise and fall, completing the lifting and lowering of the support mechanism 5. The first frame body 405, the second frame body 406 and the third frame body 407 respectively drive the support mechanism 5 to rise and fall, and expand the gap between the support mechanisms 5. The first rotating wheel 4010 and the second rotating wheel 4011 are preferably gears.

[0035] The other end of the connection block 503 is provided with a support plate 501 , and there are three support plates 501 , which are respectively arranged from bottom to top.

[0036] Sliding blocks 502 are provided on both sides of the support plate 501 , and sliding grooves 7 are provided on both sides of the interior of the photovoltaic grid-connected device box 1 , and the sliding blocks 502 are slidably connected to the sliding grooves 7 .

[0037] The end faces of the support plate 501 are provided with fixing holes 504 , the bottom end of the photovoltaic grid-connected device box 1 is provided with heat dissipation holes 8 , the fixing holes 504 are coaxial with the heat dissipation holes 8 , the top of the support plate 501 is provided with an organic body 6 which is snapped in through the fixing holes 504 .

[0038] When in use, the first frame 405, the second frame 406 and the third frame 407 are connected to the support plate 501 through the connecting block 503 when they are lifted or lowered, and then the support plate 501 is driven by the connecting block 503 to move up and down, and the sliding blocks 502 on both sides of the support plate 501 slide in the sliding groove 7. When the sliding blocks 502 slide in the sliding groove 7, the position of the lifting mechanism 4 is limited to prevent the motor 401 from driving the threaded rod 402 to rotate, and the lifting plate 404 is rotated during the process of the threaded rod 402 rotating the lifting plate 404 to lift and lower, so as to ensure that the lifting mechanism 4 only moves up and down. At the same time, the sliding groove 7 limits the position of the support plate 501 and the lifting plate 404 to prevent the lifting plate 404 from rising too high, and at the same time prevent the first rotating wheel 4010 and the second rotating wheel 4011 from detaching from each rack, and the lifting mechanism 4 cannot be used. The fixing hole 504 on the support plate 501 is clamped and fixed to the body 6 to prevent the body 6 from sliding on the support plate 501 when moving up and down.

[0039] The heat dissipation mechanism 2 includes a channel 201, which is arranged at the top of the photovoltaic grid-connected device box 1 and passes through a side wall of the photovoltaic grid-connected device box 1. An air outlet 205 is opened at the bottom of the channel 201, and the air outlet 205 is located inside the photovoltaic grid-connected device box 1.

[0040] Inside and outside the channel 201, there are a dust screen 202, a fan 203 and a ventilation cover 204 in sequence.

[0041] During use, the temperature inside the photovoltaic grid-connected device box 1 is detected by the temperature sensor 3. When a certain temperature is reached, the fan 203 is started to bring cold air into the channel 201 through the ventilation hood 204. The cold air is first filtered through the dustproof net 202 to prevent dust from being mixed in the cold air. The dust enters the photovoltaic grid-connected device box 1 and causes damage to the body 6. Then, the cold air enters the photovoltaic grid-connected device box 1 through the air outlet 205 to cool down the inside of the photovoltaic grid-connected device box 1. The cold air enters the photovoltaic grid-connected device box 1 and flows into the bottom of the photovoltaic grid-connected device box 1 through the fixing hole 504 of the support plate 501. When the cold air passes through the fixing hole 504, it will take away the heat on the surface of the body 6, thereby achieving the effect of cooling the body 6. Then, the cold air is discharged through the heat dissipation hole 8 at the bottom of the photovoltaic grid-connected device box 1. Because the fixing hole 504 is coaxial with the heat dissipation hole 8, the hot air can be brought out of the photovoltaic grid-connected device box 1 more quickly, thereby achieving the effect of rapid cooling.

[0042] Note: the temperature sensor 3 and the motor 401 are controlled by an external controller. When the temperature of the upper side of the photovoltaic grid-connected device box 1 reaches a certain temperature, the heat dissipation mechanism 2 is started. When the temperature of the lower side of the photovoltaic grid-connected device box 1 reaches a certain temperature, the lifting mechanism 4 is started to further accelerate the heat dissipation inside the photovoltaic grid-connected device box 1.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
